Please don't send me anything to review that has a fake latex watermark (e.g. in contrast to a subtle and elegant real watermark that's part of the paper). The reasons:
* You would like all my brain cells to be focused on your writing, rather than diverting some to separate the watermark text from the content of your work.
* It's a major pet peeve, and I'll be annoyed.
* Trees will die unnecessarily when I print out the document a second time, once you give me a version without the watermark, to avoid both of the above.
Note that there are various CMU thesis templates hanging around that have a fake watermark, including (unfortunately) the one Google points you to if you search for "cmu scs thesis template." I can't imagine why anyone thinks this is a good idea. In any case, either don't use these templates or modify them to remove the fake watermark.
If you want to mark each page of a document as "draft" or with a date, there is a very reasonable way to do it: in a header or footer.
